Forecast Discussion: Current Conditions: At 2 p.m. EDT this Friday afternoon, high pressure is bringing pleasant conditions to the area with continued good air quality. As we move into the early part of next week, warmer and more humid air will advect back into the area, resulting in deteriorating air quality. Clouds and a shower associated with a warm front will mean ozone levels remain low Sunday, but moderate readings of this pollutant are likely early next week as temperatures climb into the middle and upper 80s. For tonight, expect a mostly clear sky with low temperatures near 60 degrees. A temperature inversion will send fine particulate to the moderate range later tonight. *** Saturday's forecast: Sunshine and some clouds for Saturday with a warmer and more humid afternoon. Highs in the lower to middle 80s. Ozone concentrations will remain in the upper good range, but overall averages for PM2.5 will be in the lower moderate range. Increasing cloudiness Saturday night with lows in the lower to middle 60s. *** Sunday's forecast: Clouds most of the day on Sunday will limit ozone formation to the upper good range, but enough low level moisture will be present to keep PM2.5 moderate. A couple of showers and a thunderstorm will pop in parts of the area. *** Monday's forecast: Clouds will yield to more sunshine to start off the new week, and with moderate levels of humidity and light southwest winds, fine particulate will be moderate. Increasing sunshine will also push ozone into moderate territory. *** Extended forecast: More sunshine than clouds are expected during the long range period with temperatures well above average for early September. Both fine particulate and ozone are expected to be in the moderate range, but local emissions can push levels of these pollutants a little higher. We will continue to monitor the forecasts as we move on into the middle of next week.---McAuliffe
